Definitions

  • the present invention relates to a manually and automatically operated lock, in particular for rolling gates.
  • the aim of the present invention is to solve the hereinabove mentioned problem by providing a manually and automatically operated lock, in particular for rolling gates, which can be operated both manually and automatically, in particular electrically, in a very simple way, without the need of pre-fitting distinct locking means.
  • a main object of the present invention is to provide such a manually and electrically operated lock which is very simple construction-wise and can also be fitted to existing locking systems.
  • Another object of the present invention is to provide such a lock which can be easily and quickly coupled to existing alarm systems and which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • a manually and automatically operated lock in particular for rolling gates, characterized in that said lock comprises, inside a holding body, an electric motor driving, through a gear train, a pair of side rods, there being moreover provided a key cylinder cooperating with an intermediate element of said gear train, for disengaging, under the control of a key, the kinematic coupling of said electric motor with said side rods.
  • the manually and automatically operated lock in particular for rolling gates, according to the invention, comprises, inside a holding body thereof, of substantially box-like shape, and indicated overally at the reference number 1, an electric motor 2 which, advantageously, can also be remotely operated and is provided with an unlocking code, of electronic type, of a high safety type.
  • the electric motor 2 is coupled, through a driving or kinematic train, indicated overally at the reference number 3 and which will be disclosed in a more detailed way hereinafter, to a pair of side rods 4, arranged opposite to one another and slidingly associated with the body 1.
  • the kinematic train 3 comprises a small pignon 10, associated with the driving shaft of the electric motor 2, and engaging with a bevel tooth arrangement 11 of a first gear 12 having a reduced diameter spur tooth arrangement 13, engaging with a second gear 14, of greater diameter, engaging with the smaller tooth arrangement of a third gear 15.
  • the first, second and third gears 13, 14 and 15 provide a motor-reducing unit with a high reduction ratio.
  • the third gear 15 engages with an intermediate element, indicated overally at the reference number 20, which comprises a first portion 21, shown in figures 9 and 10, provided with an outer tooth arrangement 22, for coupling with the third gear 15, and being further provided with an inner slot 23 therein there is engaged a movable body 24, clearly shown in figures 7 and 8, which is provided with outer lugs 25 for coupling in rotation with the mentioned bottom portion 21.
  • the lugs 25 can engage with the inner slot 26 of a top element 27 having an outer tooth arrangement 28 therewith there engage respectively a fourth gear 29 and a fifth gear 30 in turn engaging with a first and second gear wheels 31 and 32 respectively, and being provided with eccentric pins 33 which are slidingly housed in cross slots 34 formed on the rods 4 so as to cause said rods 4 to translate as the gear wheels 31 and 32 are rotatively driven.
  • the rods 4 are caused to translate, by opening and closing displacements, since the movable body of the intermediate element 20 makes the top portion 21 and bottom portion 27 rotatively rigid with one another.
  • a key cylinder 40 which can be a conventional piston type of cylinder, which is so designed that, as the key is introduced thereinto, the movable body 24 is pushed away so as to disengage it from the bottom portion 27, thereby kinematically separating said movable body 24 from the electric motor 2.
  • the kinematic train of the electric motor is disengaged, while holding the kinematic coupling provided by the outer tooth arrangement 28 with the rod driving gear wheels.
  • a tooth 40' eccentrically arranged, which can be contact engaged by the key, thereby, as the key is turned, also the bottom portion 27 will turn.
  • the tooth 40' is provided with a tapering portion 41 which allows for the key to be easily inserted even if the key is arranged, at the start of its introducing movement, at the tooth: in fact, said tapering portion of the tooth operates as a lead-in element which facilitates the slipping of the key on the flank of the tooth thereby allowing for the lock slider to easily rotate as the lock bush is rotated.
  • the inner movable body is so designed as to return to its start position as the key is removed: to this end, there is provided a biassing spring 50 operating between the movable body and top portion 21.
  • a lock which, while having a single kinematic or operating train, for driving its side rods, can be operated both manually and electrically.
  • rod end of stroke microswitches will be provided so as to prevent the lock gears from being forced against one another which would occur if mechanical end of stroke elements would be used.
  • the lock holding body has a very reduced thickness and, accordingly, can be easily applied on rolling gates.
